摘要： In one example, a height adjustable desktop system is described that can include a work surface, a foot assembly and a linkage assembly that adjustably connects the work surface to the foot assembly allowing vertical adjustment of the work surface. The linkage assembly can include a pair of adjustment assemblies, each having a transverse linkage that maintains the work surface in a horizontal orientation as the work surface is elevated or lowered. A biasing mechanism, such as an extension spring or a torsion spring, biases the work surface toward the elevated position.

摘要： Embodiments include a balance mechanism having a first cam and a second cam configured to convert a variable force exerted by the energy storage member into a substantially constant force applied to a mounting portion. The balance mechanism may be useful for balancing forces such that a user can set the height of an electronic display and/or other equipment attached to the balance mechanism at a number of heights within the range of travel allowed by the mechanism. Lift mechanisms, display positioning apparatuses, and height adjustable desks incorporating a multi-cam balance mechanism are also provided. A method of positioning a display is also provided.
